Canopy will require the official Oracle instantclient (basic) 12.1 to
be already installed on the server, correctly configured in ldconfig
and sqlplus must be available in the standard PATH. If not, Canopy
will fail to connect to the Oracle DB stating that
libclntsh.so.12.1 cannot be found.

Instead of step 1 of the Configuration
section the user should (as root) edit /etc/canopy/canopy.ini.
